The public can monitor the baby penguin's progress at www.penguinnestcam.org and visitors to the aviary and watch the parents, Sidney and Bette, sharing nesting duties. A second egg is expected to hatch this week.

The father of the chicks, Sidney, is named for Sidney Crosby, the star of the city's National Hockey League team, the Pittsburgh Penguins.

The chicks will be named after DNA tests can determine their gender a few weeks after birth.
